In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation.

parasitoid, an insect whose larvae feed and develop within or on the bodies of other arthropods. Each parasitoid larva develops on a single individual and eventually kills that host. Most parasitoids are wasps, but some flies and a small number of beetles, moths, lacewings, and even one caddisfly species have evolved to be parasitoids.

Parasitoids are often called parasites, but the term parasitoid is more technically correct. Most beneficial insect parasitoids are wasps or flies, although some rove beetles (see Predators) and other insects may have life stages that are parasitoids.

2023年8月16日 · Parasitoids are small insects whose immature stages develop either within or attached to the outside of other insects, referred to as hosts. Parasitoids eventually kill the host they feed on, as opposed to parasites like fleas and …

2023年11月9日 · Parasitoids are a diverse and ecologically significant group that has young which develop on or within a host and eventually kill it. They differ from true parasites that derive nutrients from hosts. There are estimated to be over 600,000 global parasitoid species, predominantly wasps, flies, beetles, and mites.

Parasitoids are often called parasites, but the term parasitoid is more technically correct. Most beneficial insect parasitoids are wasps or flies, although some rove beetles (see Predators) and other insects may have life stages that are parasitoids.

A parasitoid is a type of animal that has a life history intermediate between that of a predator and prey. In general, parasitoids are invariably insects and their larvae feed at the expense of other insects, with the exception of a few species that attack different types of arthropods or mollusks.

2004年6月22日 · What is a parasitoid? It is an insect whose larvae develop by feeding on the bodies of other arthropods; like a parasite they require just a single host to complete their development, but like a predator they invariably kill their host.

2021年9月19日 · parasitoid noun, plural parasitoids - an insect that, in the larval stage, feeds off of the tissues of its host (as does a parasite), but this feeding normally results in death of the host. Thus a parasitoid is in some ways a predator as well.

2021年2月27日 · Parasitodism is a form of parasitism wherein the parasitic organism lives on or inside the host to spend a phase of its life cycle, and often causing the death of its host. This parasitic organism is referred to as a parasitoid. Certain insect species are parasitoids. A majority of them are in the Hymenoptera.
